Superduo DUETS! The Superduo shape you know and love has new dual-color options which feature two glass tones fused together in one bead. DUETS capitalize on Superduo’s hole positioning which accentuates the edges of the bead. Visually, this creates new textures where one can expand upon the color relationships within the hundreds of monotone Superduo shades and primary colours as well as play with the DUETS unique characteristic… creating shifting color schemes!
